How I Built an Autonomous AI Agent That Earns USDC While I Sleep

说明与用途

在 Cloudflare Workers 上创建了一个无状态服务，使用 x402 处理 USDC 微支付，并将资金自动转入 Base 钱包，实现被动收入。

问题

Create a self‑paying AI service that charges a micro‑payment per call and automatically settles in USDC on Base.

结果

A stateless, low‑latency AI endpoint that automatically earns USDC per call, with payments routed directly to a Base wallet and no custodial risk.

工作流

• 1. Client sends JSON POST to Worker URL with question.
• 2. x402 middleware checks Payment header, verifies signed USDC on Base, returns 402 if invalid.
• 3. If payment valid, Worker instantiates Agent class and calls OpenAI chat completion.
• 4. Agent returns answer, Worker sends JSON response.
• 5. x402 forwards USDC to destination address; Worker never holds funds.

证据

The result is a service that charges $0.01–$0.10 per call in USDC on the Base L2, with the earnings accruing to a wallet I control.

来源

The Worker itself never holds funds; the x402 library forwards the USDC directly to the destination address encoded in the payment header.
